Yes this is one of the things that always annoys me with autotools's
The tarballs created by 'make distcheck' contain directory entries
which are created every time you run make distcheck and thus have
different creation times every time. So you end up with different tar
Moreover gzip also adds the mtime of the compressed file to its
header, so even if you generate the same archive twice (whith the same
checksums before compression) you end up with 2 different files once
gzip'd. bzip2 doesn't include the timestamp so isn't affected by this
